I had 1 gb ddr2 ram in my notebook(emachines d525).Today i went to put one more stick of 1gb ram. It was hard to find it, but finally i found the shop.I was really in a hurry so i didn't check anything.
Now when i checked back home it says i have only 1.5gb ram. I checked on windows task manager(total 1,499,916),on crucial.com it says i have 1gb and other stick 512mb,on dxdiag it says 1,49gb ram and on control panel/system it also shows 1.49ram. Was i hassled(if i had i'll go back to shop tommorow) or is that usual for ddr2 ram? Also, i have windows xp sp3 32bit.
It does appear that you were given the wrong ram module (on purpose or not I can't say but...). You do want a 1GB module (I assume), I'd go back and exchange it - you might check your receipt to see if you were charged for a 1GB module (or if it says) you may also want to check the label on the module to see if it doesn't claim to be 1GB (could be a faulty module)
